PNEUMATIC STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 663,150, dated D c mb 4, 1900.

Application filed February 14,1899. Serial No. 705.469. 1N0 model.)

nishes a blast of air to a movable pipe which conveys the straw from a threshing-machine and deposits it upon a stack or in a mow by means of the blast of air forced through said pipe by the fan.

The objects of my invention are, first, to

provide a lighter pipe than those heretofore used; second, an improved construction of the pipe by which the straw and chaff may be deposited at any point in the radius of the pipe; third, a pipe which can deposit straw nearer to the threshing-machine than those previously used; fourth, a construction giving greater rigidity and which will not be impeded in its movements by dents or injuries to same, and, fifth, to provide an improved fan which shall not break the straw and shall give a stronger blast with the expenditure of less power than the forms of fan heretofore used. I attain these objects by the mechanism illustrated in the drawings, in which Figure 1 is a side elevation of a stackerpipe embodying my invention. Fig. 2 is atop plan View of the pipe shown in Fig. 1. Fig. 3 is a perspective view on a smaller scale. Fig. 4 is a vertical sectional view through the joint between the elbows.

Similar letters refer to similar parts in the several views.

Taking Fig. 1, I is a turn-table, on which the pipe, composed of the two sections B C, is supported. e is a hand-wheel suitably connected to a yoke embracing said pipe and pivoted, as shown. By means of the hand-wheel 6 suitable gear (not shown) is operated, by which the pipe is elevated or lowered, the same being supported upon the turn-table and the pipe being held by the collar K, pivoted to the turn-table at .I. The turn-table I is re- The stacker-pipe is made up of two sections of pipe B and 0. They are each provided with an elbow, the elbow g being rigidly attached to the section B, while the elbow h is rigidly attached to section 0. The two elbows are joined by two collars at D. These are connected by a ball-bearin g swiveljoint hereinafter described. (1 represents a shaft provided with a suitable operatingcrank and upon its upper extremity a worm .d, which meshes into a worm-gear a upon the collar of the elbow 72,. By turning this shaft the collar attached to elbow h is made to revolve, carrying with it the section of pipe 0. The crankfcontrols the cables f, leading to the hood L, and by which said hood is opened or closed. The worm end of the shaft is j ournaled in a bearing (1 secured to the elbow g, portions of the bearing preferably extending at each end of the worm and preventing endwise movement of the same.

The operation of the pipe is as follows: By means of the crank e the whole stacker-pipe is elevated or depressed. By suitable means above alluded to the turn-table I is made to revolve, so carrying the whole stacker-pipe through an arc of a circle of which said table is the center. By turning the crank shown the shaft 01 is turned, by which the upper section of pipe carried by the elbow h is made to turn in a horizontal plane, and the hood L, through which the straw is discharged, can be brought close to the threshing-machine, or the upper section 0 being revolved in an opposite direction the whole pipe may be brought into a straight line. By this construction it is seen the hood L may be given a great range and straw can be delivered over a greater area than by the construction of stacker-pipes previously employed.

My construction is superior to a telescoping device, because no pipe is needed to form the connecting-section of the two portions of the pipe. In a telescoping pipe several feet of the upper pipe must be inclosed in the lower pipe to secure support. Any jamming of the pipe will not affect its ease of motion, while with a telescoping pipe a slight jam makes it impossible for one section to slide within the other.

In Fig. 2 sections of the elbows g and h are shown. The ball 0 runs upon a grooved track, that portion marked 4; being attached to the at the same time the section G is easily re-,,

volved upon the section B.

The elbows, collars, 850., can be assembled in any desired or approved manner. For instance,the collard can be made in sectionsand secured together and to the elbow h around the inner collar 1) and the balls 0.

What I claim as new, and desire to protect by Letters Patent, is

1. In a pneumatic stacker, the combination of suitable supporting means, a pipe-section supported thereby having at its end an elbow, a second elongated straight rigid pipe-section supported by said first pipe-section and having an elbow having a swivel connection with the first-pipe-section elbow, substantially as described.

2. In a pneumatic stacker, the combination of a rigid pipe-section having an elbow, a second section supported by the first pipe-section and having an elbow, a swivel connection between said elbows, and means for swinging said second section from a position over and in line with the first section to a position outwardly beyond and in the longitudinal plane of said first section, substantially as described.

3. In a pneumatic stacker-pipe, the combination of an inner rigid pipe-section having an elbow, an outer rigid pipe-section supported by said inner pipe-section and having an elbow, a swivel connection between said elbows, and means for swinging said outer pipe-section on said swivel connection in a complete circle whereby the delivery end of the pipe can be adjusted to difterent distances from the feed end of the pipe, substan tially as described.

a. In a pneumatic stacker, the combination of an inner pipe-section, having an elbow, an outer pipe-section supported by said inner section and having an elbow, a swivel connection between said elbows, a gear carried by said outer-section elbow, a pinion mounted on the inner section and meshing with said gear, and means for operating said pinion for swinging said outer section whereby the delivery end of the pipe can be adjusted to different distances from the feed end of the pipe, substantially as described.

5. In a pneumatic stacker-pipe, the combination of an inner pipe-section having an elbow, an outer pipe-section having an elbow, a ball-race secured to one of said elbows, a ball-race secured to the other elbow and provided on its outer part with gear-teeth, a gear mounted on the first-mentioned pipe-section and meshing with the gear-teeth on said ballrace, means for operating said gear and balls between said races, substantially as described.

6. In a pneumatic stacker-pipe, the combination of an inner pipe-section, having an elbow, an outer pipe-section having an elbow, a ball-bearing connection between said elbows the same constituting the means for support ing and retaining the outer pipe-section on the inner pipe-section, and means for swinging said outer pipe-section on the inner pipesection, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE F. CONNER.
